Testbed

Software Defined Visible Light Communications

Overview: We have adapted work from Software Defined Radio to be applicable to the development and evaluation of future Visible Light Communications systems. Here we highlight the SDVLC system and testbed deployed as part of LESA.

We have modified a SDR from RF to compatible with both GNU Radio and Simulink using an optical front end comprised of an illumination grade luminaire from Cree Lighting. We have implemented modulation techniques for dynamic adaptation to lighting conditions such that average optical output power is varied to meet illumination requirements. READ MORE.
